INSTALLATION

Location

  • Do not install it on the outside wall.
  • Do not install in areas with direct heat sources.
  • Do not install near any air discharge grill.
  • Do not install in areas exposed to direct sunlight.
  • Ensure the Room Controller has sufficient air circulation.
  • Ensure the wall surface is flat and clean.

Installation

  1. Remove the security screw (if any) on the bottom of the Room Controller cover.
  2. Open the unit by pulling on the bottom side of the Room Controller (Figure 1).Viconics-VT8650-Programmable-Thermostat-fig.1
  3. Read the FCC ID and IC label installed on the cover before installing any wireless product.
  4. Ensure the correct side of the base faces up.
  5. Pull cables 6in ( 15cm ) out from the wall.
  6. Align the base and mark the location of two mounting holes on the wall (Figure 2).Viconics-VT8650-Programmable-Thermostat-fig.2
  7. Install anchors in the wall.
  8. Insert cable in the central hole of the base.
  9. Insert screws in mounting holes on each side of the base.
  10. Strip each wire 1/4in ( 0.6cm) from the end.
  11. Insert each wire and screw according to the wiring chart (next page).
  12. Gently push excess wiring back into the hole.
  13. Gently align the cover to the top of the base and snap in place from the bottom (Figure 3).Viconics-VT8650-Programmable-Thermostat-fig.3
  14. Install security screw.
  • If replacing an existing Room Controller label wires before removal of Controller.
  • Electronic controls are static-sensitive devices. Discharge yourself correctly before manipulating and installing the Room Controller.
  • A short circuit or wrong wiring may permanently damage the Controller or equipment.
  • All VT8600 series controls are designed for use as operating controls only and are not safety devices. Tampering with the devices or unintended application of the devices will result in a void of warranty.
  • This device must be installed to provide a separation distance of at least 8in (20cm) from all persons and must not be collocated or operating in conjunction with any other antenna or transmitter.

CONFIGURABLE BI/UI UNIVERSAL INPUTS OVERVIEW

Universal input #16 can be configured for the following binary functions:

  1. (None): No function associated with the input
  2. (Rem NSB): remote NSB timer clock input. The scheduling is set as per the binary input. It provides low-cost setback operation via a dry contact.
    Contact opened = Occupied
    Contact closed = Unoccupied
  3. (Motion NO) and (Motion NC): Advanced PIR occupancy functions using a normally open (NO) or normally closed (NC) remote PIR motion sensor. Occupancy mode is now set as per the applied PIR function and configuration. This document will provide the installers and system designers with detailed examples of applications, parameter configuration information, sequence of operation, troubleshooting, and diagnostic help required for the proper usage of the onboard PIR sensor.
  4. (Window) EMS: Forces the system to disable any current heating or cooling action by the Room Controller. The mode stays the same and the current setpoints are the same occupied setpoints. Only the outputs are disabled. There is a Door/Window alarm displayed on the Room Controller to indicate to the local tenant that the door/window needs to be closed for cooling or heating to resume. Use NC contact.
    Contact opened = System disabled with local Window Alarm
    Contact closed = System enabled
  5. (Fan lock): a Fan lock alarm short text message shows on the Room Controller screen when the input is not energized. Used in conjunction with a local airflow sensor connected to the input. Locks out the Room Controller heating and cooling action if no airflow is detected 10 seconds after the fan ( G terminal ) is energized.
    Contact opened = no airflow
    Contact closed = airflow present

Universal input #17 can be configured for the following binary functions:

  1. (None): No function associated with the input. Input can be used for remote network monitoring.
  2. (Door Dry) Door contact and motion detector: This configuration is only functional if binary input #1 is set to Motion NO or Motion NC or an onboard PIR sensor is used. With this sequence enabled, the occupancy is now dictated through those 2 inputs. Any motion detected will set the zone to occupied status. The zone remains permanently in occupied mode until the door contact switch opens momentarily. The Room Controller will then go in stand-by mode. If more movements are detected, the occupied mode will resume. While the door is opened, any movements detected by the remote PIR sensor or the onboard PIR sensor will be ignored. Use a Normally Closed contact switching device.
    Contact opened = Door opened
    Contact closed = Door closed
  3. (Override): Temporary override remote contact. Disables all override menu functions of the Room Controller. The override function is now controlled by a manual remote momentarily closed contact. When configured in this mode, the input operates in a toggle mode. With this function enabled it is now possible to toggle between unoccupied & occupied setpoints for the amount of time set by the parameter (TOccTime) temporary occupancy time. When Override is enabled, an Override status message will be displayed
  4. (Filter): A filter alarm short text message shows on the Room Controller screen when the input is energized
  5. (Service): A service alarm short text message shows on the Room Controller screen when the input is energized.

APPENDIX A TERMINAL CORRESPONDENCE
The terminals of a VT8600 are identified differently and have a wider range of possible functions compared to those of any of the VT7000 series Room Controllers. There is a direct correspondence of functions between the terminals of the VT7000 series and the VT8600 series. Consult the table below to verify the appropriate terminal when replacing a VT7000 Room Controller with a VT8600 Room Controller.

APPENDIX B POWER OUTAGE CLOCK RESET
In the event of a power outage, VT8600 Room Controllers will retain the correct time as long as the duration of the power outage is not prolonged. Depending on the duration of the power outage, the Room Controller’s internal clock may need to be updated or reset completely. The following table gives an indication of the expected clock performance after a power outage.
